During the day the stars are still tright here, you justcan"t check out them bereason the skies is so bbest. Forinstance, it"s a lot less complicated to view the glow of acandle in the dark than in the light. It isconstantly difficult to feeling tiny transforms to somethingthat is already substantial to begin through. For example,in a noisy room you more than likely can not hear a drippingfaucet, yet as soon as every little thing else is quiet then youcan hear the drip, also though the dripping hasn"tgained any kind of louder. Its simply less complicated to hearsomepoint soft in a silent background, than it isto hear somepoint soft in a noisy background. In the very same method it"s simpler to watch the dimstarlight with a dark background than it is to seethe same dim starlight on a bideal background.

Answer 2:

Try noticing the skies at night throughout the nextmonth.Compare how many kind of stars you deserve to see currently, whenthe moon is not up (until about midnight orlater), to a few weeks from currently once the moon isfull aget. Now imagine having actually the sunlight in the skyinstead of the full moon. How many type of stars carry out youthink you should be able to see?You couldadditionally watch the skies as the sunlight is establishing. As thesky starts to darken, as soon as have the right to you first seestars? How bappropriate does the skies seem to be at thistime once compared with daytime? Once the sky istotally dark, exactly how bbest are the first stars youcould watch compared to the rest of the stars in thesky?

Answer 3:

The reason that you cannot check out stars in the time of thedaytime is that the sun"s rays overpower the faintlight we check out from the stars. Throughout the night,once the sun"s rays are blocked by the other sideof the earth, it is possible to watch the faintlight of the stars shining in space. You canwatch this change if you watch the suncollection on aclear night, as the sun"s rays end up being fainter andfainter (and it becomes dawn on the other side ofthe earth), you can start to view the first hint ofthe brightest stars. You will likewise notice that,mainly speaking, the initially stars to appear willbe those farthest ameans from the setting sunlight (wherethe sky is darkest at that time).Hope thathelps!

Answer 4:

This question can be partly answered by severalresults. First, the humale eye is sensitive tolight over an substantial range of intensities.Typical "bright" stars are actually exceptionally dimcompared to the brightness of the sun -- about atrillion 10^12 times dimmer. The brightness ofobjects illuminated by the sunlight typically 10 to 100times dimmer than it is -- but that still makesthe an huge trouble for the eye. (It has atleast two mechanisms for light accommodation-- theiris which basic stops a fraction of the lightlike a camera lens, and also chemical transforms whichimprove the cells particular to night vision. --this takes some 10 to 20 minutes and also unless youwalk quickly from dim to bideal or vice versa youwon"t notice it.) So the first problem is thatyour eye -- to permit you to view, will certainly mitigate itssensitivity once tbelow is bideal lightcurrent.Secondly, the atmosphere of theearth has actually many fine particles of dust which areso tiny they never settle to the ground. Thesedust pshort articles scatter a little component of the lightfrom the sun in random directions, and thesystem for scattering functions much better for shorter(bluer) wavelengths. This is why the skies is blueand also why the sun seems to redden as it sets -- ithas actually a longer course in the air -- so even more of theblue light is lost, then green ... and so on.By themethod, clouds are made of a lot bigger bits, so theyscatter visible light fairly evenly -- making themappear white. (But not to also much longer light likeinfrared -- which deserve to peer throughclouds).Both processes make seeing starsin the daytime extremely difficult. However, if you happento be in a deep well, through dark walls so that youjust watch a little little of sky, and the remainder of youvisual area is dark, you could check out some brightstars in the time of the day.... So, carry out you think that theastronauts have the right to view the stars during the day fromthe moon?

Answer 5:

The factor we can"t view the stars in the time of the dayis because as soon as the sun is up, it is so muchbrighter than the stars that our eyes can not pickthem out of the skies. You could think that youcould check out stars throughout the day if you looked AWAYfrom the sunlight, but the sun"s light is spread outeverywhere the skies by our environment, which is partof the factor why the sky is blue in the time of the day(it"s clear at night, right?)Here"s aquestion for you. Stars, just prefer the sun, tendto climb in the east and set in the west. Why dothey do that?If that"s as well easy, here"s amuch harder question. The sun rises in the eastand sets in the west. But in the summer, the sunrises in the northeastern and also sets in the northwest,and in the winter the sun rises in the southeastand sets in the southwest. (In the spring andloss, the sunlight rises and also sets more or less directlyin the east and also west.) How or why does thishappen? (Drawing pictures may aid.)

Answer 6:

In the day the stars are still tbelow, yet youcannot view them bereason they are so a lot fainterthan the sunlight that is scattered by ourenvironment. If the Planet had no atmosphere, thenour daytime skies would be black like at night,other than the sunlight would certainly be a huge spotlight shiningdown at us. In such an unpleasant human being we mightcheck out stars in the time of the day. But since we have actually ansetting, the sun"s light scatters and also offers usa beautiful blue glow from almost everywhere, not simply fromwbelow the sun is. In various other words, even if youlook ameans from the sunlight you are still seeing thesun"s light that has bounced off of some particlein the environment, and that light is much brighterthan the light from the stars.Maybe yourteacher have the right to help you attempt to discover out what theparticles are in our setting that scatter thesun"s light and why the scattered light is blue! WHY IS THE SKY BLUE?

Answer 7:

It is feasible to watch a few of the brightest starsduring the day. In truth, tbelow is one star thatdeserve to sometimes be viewed during the daytime, however cannever before be viewed at night! Can you guess which one?(Hint -- it"s the closest star.)Tright here areat least two difficulties through observing stars duringthe day time. First, stars are very faintcompared to the light from the sunlight (the neareststar). Our eyes are adjusted to sunlight duringthe day, and much much less sensitive. Not only doesthe iris of the eye contract from the highintensity sunlight, however the retina becomes muchmuch less sensitive to light also. A clear sky istransparent to starlight, but the blue shade fromscattered sunlight is bbest enough to overpowerfeeble stars. The other trouble is thatyour eye has actually obstacle focusing to infinity whenyou are looking at a featureless blue sky. If youare trying to view tiny, faint things choose starsit is instrumental that your eye be focused exactly.However, if you look at a blue skies tbelow is noreferral object for your eye to emphasis on and also itis tough to effectively focus on a star.Nonetheless, it is possible to see somestars in daylight. The stars need to be bappropriate, suchas actually Sirius, Arcturus, Vega, Capella, Rigel, etc.You also need to know exactly where to look, indevelopment. Finally, it helps if tright here is some verydistant object ideal beside the star that you canemphasis your vision on. Aldebaran is a great star totry to view bereason it lies near the plane of theecliptic, and also the moon passes extremely near it onceevery 28 days.


You are watching: We do not see stars in the daytime because

(Often the moon occults Aldebaran,that is, it passes between the Earth and thestar.) If the moon is incredibly close to Aldebaran duringthe day, you simply can have the ability to view it if youhave great eyesight.
